Three Ways How to Graph a Line

Graphing a line in the xy-axis is one of the most basic skills in algebra that you should learn. In this lesson, we are going to go over three methods that are commonly used. Learn each method and you’ll be able to decide which one works better depending on the given problem.

I have created separate lessons for each. Click the link at the bottom of each method.

Method 1: Constructing a Table of Values

This is the most straightforward method in graphing a line. What we need to do is to select some values of x and then evaluate those values in the given equation to get the corresponding values of y. Finally, plot those points in the xy-axis, and connect them with a straight edge.

Method 3: Connecting the x and y-Intercepts

Remember, we only need two points to graph a line. With that idea, we take advantage of the two “convenient” points which can easily be solved algebraically from the equation of the line; namely, the x-intercept (x, 0) and y-intercept (0, y).
